摘要: 相干斑抑制是合成孔径雷达(SAR)图像和极化SAR图像后处理的首要问题。该文针对最优的极化相干斑抑制滤波器极化白化滤波器(PWF)仅输出一个强度图像的缺陷,对 PWF进行了改进,得到了各个极化通道的强度图像。Abstract: Speckle reduction is the primary problem of SAR (Synthetic Aperture Radar) and polarimetric SAR imagery post-processing. Because the optimal polarimetric coherent speckle filtering-Polarimetric Whitening Filtering (PWF) has the drawback of only outputting a intensity image, this paper improves on it and get all polarimetric channel intensity images.
